5 Recommendation Reduce temperature rise limits Due to frequent overloading in service, life deteriorates. Contributes to poor reliability. The current temperature rise limits 50/55 0 C over the ambient of 50 0 C of top oil and winding respectively. Temperature rise limits revised to 35/40 0 C over the ambient of 50 0 C of top oil and winding respectively. Implication on cost average of 3%. Similar changes helped GEB to reduce failure rate from 27% to 20%.

24 In order to create market pull, the government could buy only star rated products, i.e. the highest energy efficiency products. The standards should be futuristic since there is also a time frame required for phasing out old products and introduction of efficient products. A time frame of 2-3 years was suggested. Labeling would be the first activity to be taken up in these products. VISION OF S & L PROGRAMME ( CONTINUED)

27 FTL Technical Committee Recommendations For energy labeling 3 parameters should be considered which would provide efficacy from both efficiency as well as life: Lumens at 100 hrs.(initial lumens) Lumen/watt Lumen depreciation @ 2000 hours Lumen/watt Lumen depreciation @ 70 % life (3500) hours Lumen/watt. Test Procedure: relevant BIS test procedures including amendments meet all the minimum requirements of BIS to qualify for labelling BIS certification or a quality control certification, a prequalification for labelling

28 For 18W we have considered 940 lumens in place of 1015 lumens in BIS since this has been agreed in the last meeting of the BIS. Based on the visit of the technical team to the four Laboratories, the recommendations of the technical committee is to go for testing at NPL & ERDA after ascertaining Proficiency testing in both the Laboratories. Accreditation of NPL with NABL is under process. The 3200 lumen output lamps (Triband) was also included for testing and BIS has also agreed to go in for the standards in the last meeting FTL Technical Committee Recommendations ( Continued)

29 10 lamps were tested at manufacturers laboratory as well as ERDA to get comparative readings/calibration before full scale testing begins (Proficiency Testing). There were certain differences in the optical measurements in the three laboratories but these are with in the z score of proficiency testing. Since the measurements are against a standard reference lamp, it was felt necessary to ensure the quality of reference lamp. BEE to take up with NPL The lighting industry had agreed to align with ERDA laboratory FTL Technical Committee Recommendations ( Continued)

31 Basis Values for the 100 hours efficacy was worked out taking into consideration that all Wattages and their energy efficacy is reflected the star rating plan. The values of IS with permissible tolerances for different wattages were used to arrive at the boundaries. Efforts were made to differentiate 20 W & 18 W, 40 W & 36 W and halo phosphates and Tri phosphates Star rating plan would ensure efficiency purchases. The cut off % for these categories have been fixed in such a way the categories of lamps operating with good quality control as well as above the minimum threshold would fall in the appropriate levels.
